Abstract
BACKGROUND Patients with resistant hypertension are the group of hypertensive patients with the highest cardiovascular risk. METHODS All rules and guidelines for treatment of hypertension should be followed strictly to obtain blood pressure (BP) control in resistant hypertension. The mainstay of treatment of hypertension, also for resistant hypertension, is pharmacological treatment, which should be tailored to each patient's specific phenotype. Therefore, it is pivotal to assess nonadherence to pharmacological treatment as this remains the most challenging problem to investigate and manage in the setting of resistant hypertension. RESULTS Once adherence has been confirmed, patients must be thoroughly worked-up for secondary causes of hypertension. Until such possible specific causes have been clarified, the diagnosis is apparent treatment-resistant hypertension (TRH). Surprisingly few patients remain with true TRH when the various secondary causes and adherence problems have been detected and resolved. Refractory hypertension is a term used to characterize the treatment resistance in hypertensive patients using ≥5 antihypertensive drugs. All pressor mechanisms may then need blockage before their BPs are reasonably controlled. CONCLUSIONS Patients with resistant hypertension need careful and sustained follow-up and review of their medications and dosages at each term since medication adherence is a very dynamic process.

Abstract
Objective Group the barriers to knowledge, treatment, and control of hypertension in patients in Latin America through a scoping review. Methods A scoping review was conducted in accordance with the Arksey and O'Malley methodological framework and the PRISMA guidelines for systematic reviews and meta-analyses. Searches were carried out in the PubMed, Virtual Health Library, and Scopus databases. Blind and independent selection was conducted in the RAYYAN QCRI application. Finally, the results of the selected studies were addressed narratively. Results Eight qualitative and quantitative studies that fit the research question were included. The most frequently described barriers are systemic barriers that hinder comprehensive and equitable access to health care and medication, as well as a lack of educational programs, personalized interventions to improve adherence to treatments, and lifestyle changes. Economic factors are critical in Latin America, hindering access to the health system and changes to lifestyles due to the costs of transportation, medical appointments, and medicines. Conclusions The detected barriers affect all dimensions of adherence to treatment; among the most important barriers are decision makers who lack education and positioning with respect to care of hypertension.

Abstract
Background Measurement of serum concentrations of drugs is a novelty found useful in detecting poor drug adherence in patients taking ≥2 antihypertensive agents. Regarding patients with treatment-resistant hypertension, we previously based our assessment on directly observed therapy. The present study aimed to investigate whether serum drug measurements in patients with resistant hypertension offer additional information regarding drug adherence, beyond that of initial assessment with directly observed therapy. Methods and Results Nineteen patients assumed to have true treatment-resistant hypertension and adherence to antihypertensive drugs based on directly observed therapy were investigated repeatedly through 7 years. Serum concentrations of antihypertensive drugs were measured by ultra-high-performance liquid chromatography-tandem mass spectrometry from blood samples taken at baseline, 6-month, 3-year, and 7-year visits. Cytochrome P450 polymorphisms, self-reported adherence and beliefs about medicine were performed as supplement investigations. Seven patients (37%) were redefined as nonadherent based on their serum concentrations during follow-up. All patients reported high adherence to medications. Nonadherent patients expressed lower necessity and higher concerns regarding intake of antihypertensive medication (P=0.003). Cytochrome P450 polymorphisms affecting metabolism of antihypertensive drugs were found in 16 patients (84%), 21% were poor metabolizers, and none were ultra-rapid metabolizers. Six of 7 patients redefined as nonadherent had cytochrome P450 polymorphisms, however, not explaining the low serum drug concentrations measured in these patients. Conclusions Our data suggest that repeated measurements of serum concentrations of antihypertensive drugs revealed nonadherence in one-third of patients previously evaluated as adherent and treatment resistant by directly observed therapy, thereby improving the accuracy of adherence evaluation.

Abstract
OBJECTIVES Hypertension is a common cause of cardiovascular morbidity and mortality. Although hypertension can be effectively controlled by blood pressure-lowering drugs, uncontrolled blood pressure is common despite use of these medications. One explanation is therapy non-adherence. Therapy non-adherence can be addressed at the individual level, the level of the healthcare provider and at the healthcare system level. Since the latter two levels are often overlooked, we wished to explore facilitators and barriers on each of these levels in relation to hypertension care for people with hypertension, with a specific focus on therapy adherence. DESIGN Qualitative study using focus groups of healthcare providers. Data were analysed using the theoretical domains framework (TDF) and the behaviour change wheel. SETTING AND PARTICIPANTS Participants were from a highly urbanised city environment (the Hague, Netherlands), and included nine primary care physicians, six practice nurses and five secondary care physicians involved in hypertension care. RESULTS Nine domains on the TDF were found to be relevant at the healthcare provider level ('knowledge', 'physical, cognitive and interpersonal skills', 'memory, attention and decision processes', 'professional, social role and identity', 'optimism', 'beliefs about consequences', 'intention', 'emotion' and 'social influences') and two domains ('resources' and 'goals') were found to be relevant at the system level. Facilitators for these domains were good interpersonal skills, paying attention to behavioural factors such as medication use, and the belief that treatment improves health outcomes. Barriers were related to time, interdisciplinary collaboration, technical and financial issues, availability of blood pressure devices and education of people with hypertension. CONCLUSIONS This study highlighted a need for better collaboration between primary and secondary care, for more team-based care including pharmacists and social workers, tools to improve interpersonal skills and more time for patient-healthcare provider communication.

Qualitative and quantitative analysis of doctor-patient interactions during andrological consultations. Andrology 2022; 10:1240-1249. [PMID: 35785424 PMCID: PMC9540423 DOI: 10.1111/andr.13225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 06/06/2022] [Accepted: 06/28/2022] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Although a trustworthy connection between doctor and patient is crucial in clinical practice, it could be hindered by different cultural and linguistic backgrounds. Moreover, an effective doctor-patient interaction could be even more challenging in andrological fields, in which psychological and social components are predominant. AIM To analyse the doctor-patient relationship in the andrological field, applying both qualitative and quantitative analyses. METHODS monocentric, cross-sectional, observational study was performed between May and December 2018. During the study, all patients aged >18 years attending the Modena Andrology Unit for couple infertility or erectile dysfunction were enrolled and the doctor-patients interaction recorded. Patients were divided into two groups depending on their medical seeking and were further divided between native and non-native speakers of Italian. All patients underwent a routine andrological examination. Every first medical consultation was audio-recorded and transcribed using "ELAN" software for socio-linguistic analysis. Transcriptions underwent qualitative analysis through conversation analysis. Then, quantitative analyses were performed, and interaction parameters underwent correlation analyses. RESULTS Twenty-five patients were enrolled. The analysis of the andrological interview allowed to recognize five consecutive phases, following a semi-standardized pattern. Patients without linguistic barriers and with infertility problems showed more autonomous contribution during the consultation. No difference arose in sexual dysfunctions group. Doctor's explanations were frequent, but when linguistic barrier was present or Italian patients seemed less talkative, explanations were shorter, and doctors tried to use other conversational mechanisms to promote understanding. Patient's variables were significantly lower compared to the doctor, considering the number of turns (p = 0.025) and their minimum (p = 0.032), maximum (p<0.001), and average durations (p<0.001). Only patient's latency was significantly higher than the doctor's (p = 0.001). CONCLUSION This is the first attempt to analyse the doctor-patient relationship in andrology using authentic audio-recorded consultations. The results confirmed that a patient-centred communication must be applied also in andrological consultations. However, the topics discussed may require more "medical formulation" to be acceptable to the participants in this context. This article is protected by copyright. All rights reserved.

Patients' perception of coercion with respect to antipsychotic treatment of psychotic disorders and its predictors. Soc Psychiatry Psychiatr Epidemiol 2021; 56:1381-1388. [PMID: 33904940 PMCID: PMC8316198 DOI: 10.1007/s00127-021-02083-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Accepted: 04/07/2021] [Indexed: 11/12/2022]
Abstract
PURPOSE The present study investigates perceived coercion in psychiatric inpatients under prescribed antipsychotic medication without a court order. The objective of this study was to investigate whether and to what extent involuntary and voluntary inpatients feel coerced to take their medication and which factors affect perceived coercion. METHODS Voluntarily and involuntarily admitted patients (55 and 36, respectively) were interviewed about the extent of perceived coercion. In addition, socio-demographic and clinical data were collected. The Admission Experience Scale (aAES) was used to assess perceived coercion concerning medication. To measure insight into illness, attitude towards medication, and symptom severity, we used a questionnaire on insight into illness (FKE-10), the Drug Attitude Inventory (DAI-10), and the Brief Psychiatric Rating Scale (BPRS-24), respectively. RESULTS Voluntarily treated patients experienced significantly less coercion when taking prescribed medication in inpatient settings than involuntarily treated patients. The experience of coercion was not related to socio-demographic or clinical variables nor to the BPRS-24 score, but to insight into illness and attitude towards medication. Patients who had experienced at least one coercive measure during the index hospital stay showed a higher level of perceived coercion. CONCLUSION Perceived coercion related to medication is dependent on insight into illness and experience of previous coercive interventions rather than on the severity of psychopathological symptoms. These findings are very similar to a previous study in a forensic psychiatric sample. Having experience of at least one coercive measure seems to be a decisive aspect of the extent of the patients' perceived coercion.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) is an integral part of patients' therapeutic experience worldwide. Among Saudi older adults, less is known about CAM utilization. OBJECTIVES To determine the prevalence, patterns, and factors associated with CAM utilization among SOA. METHODS In the Saudi National Survey for Elderly Health (SNSEH), subjects were asked about CAM use during the last twelve months before the interview. CAM use was defined as any use of herbal products, acupuncture, bloodletting, cauterization, medical massage, bones manual manipulation, honey, or religious rituals. Demographic characteristics included gender, age, marital status, region, educational level, and residence area. In addition, multiple comorbidities were included as possible factors that may be associated with CAM use. Multivariable logistic regression was used to explore factors associated with CAM utilization. All statistical analyses were done using STATA v.14. RESULTS Out of 2946 respondents, 50.4% were males, the mean age was 70.3 ± 8.3 years, and 70% were illiterate. CAM use was prevalent (62.5%). The most common CAM types were herbal products (25.4%), acupuncture (21.2%), bloodletting (12%), honey (9.5%), cauterization (7.4%), medical massage and bones manual manipulation (4%), and traditional bone setting (2.1%). In the multivariable regression, age, gender, and marital status did not have an impact on the odds of using CAM. Subjects from rural areas were 2.92 times more likely to use CAM compared with subjects in urban areas (OR = 2.92; 95%CI: 2.28-3.75). Subjects with metabolic disorders (OR = 0.50; 95% CI: 0.42-0.60) or kidney disease were less likely to use CAM (OR = 0.30; 95%CI: 0.14-0.64). About pain, CAM is used more in neck pain (OR = 1.69; 95%CI: 1.30-2.21) and also used in back pain (OR = 1.22; 95%CI: 1.03-1.46). CONCLUSIONS CAM use was very prevalent among SOA. Clinicians and pharmacists must ask about CAM use among older adults as many of CAM may interact with patients medications.

Abstract
Background Advances in treatment and increased awareness have improved the prognosis for many patients with hypertension (HTN). Resistant hypertension (RH) refers to a subset of hypertensive individuals who fail to achieve a desired blood pressure (BP) despite concurrent use of 3 different classes antihypertensive agents, one being a diuretic, and proper lifestyle changes. The prevalence and prognosis of RH are unclear owing to its heterogeneous etiologies, risk factors, and secondary comorbidities. Previous research has provided evidence that increased renal sympathetic nerve activity (RSNA) within the renal artery contributes to RH development. Renal denervation (RDN) is a procedure that attempts to ameliorate the effects of heightened RSNA via ablation renal sympathetic fibers. BP reductions associated with RDN may be attributed to decreased norepinephrine spillover, restoration of natriuresis, increasing renal blood flow, and lowering plasma renin activity. Early clinical trials perpetuated positive results, and enthusiasm grew exponentially. However, recent clinical trials have called into question RDN's efficacy. Numerous limitations must be addressed to discern the true effectiveness of RDN as a therapeutic option for RH. Objective We aimed to review the current understanding of RH, the anatomy of renal arteries, physiology of RH on renal arteries, anatomical pathways of the sympathetic involved in RH, RDN as a treatment option, and all relevant clinical trials treating RH with RDN. Methods We piloted a MEDLINE® database search of literature extending from 1980 to 2017, with emphasis on the previous five years, combining keywords such as “resistant hypertension” and
“renal denervation.” Conclusion A plethora of information is available regarding heightened RSNA leading to RH. RDN as a possible treatment option has shown a range of results. Reconciling RDN's true efficacy requires future trials to increased sites of nerve ablation, standardized protocol, increased anatomical understanding per individual basis, stricter guidelines regarding study design, increased operator experience, and integrating the use of a multielectrode catheter.

Abstract
People with diabetes often have difficulty reaching their blood pressure targets and are labelled as having resistant hypertension. Clinicians often move quickly to screen such people for secondary causes of hypertension; however, such causes are rare, and resistant hypertension usually has other explanations that are significantly more common. By using a structured approach to resistant hypertension, clinicians can assist patients to reach their target blood pressure levels. Step 1 is to determine out-of-office blood pressure measurements using home or ambulatory blood pressure monitors. Step 2 is to determine the level of adherence to prescribed medications. Step 3 is to identify interfering substances. Step 4 is to check that the prescribed medications are synergistic and optimally dosed. Finally, if all other steps fail to get patients to their blood pressure targets, we consider possible secondary causes of hypertension. This approach is particularly useful in helping people with diabetes to reach their blood pressure targets.
